Benefits of technology

[0007]The present invention provides a stereoscopic image display method and apparatus capable of removing crosstalk generated in a stereoscopic LCD device using liquid crystal shutter glasses.

Problems solved by technology

In the stereoscopic image display apparatus using the liquid crystal shutter glasses, however, crosstalk is generated due to data holding characteristics of an LCD device and resulting in a left-eye image and a right-eye image being mixed in a single frame.
This crosstalk makes the stereoscopic image display apparatus display wrong images to the left and right eyes of the viewer, thereby causing fatigue in the eyes of the viewer.

Embodiment Construction

[0035]Hereinafter, exemplary embodiments will be described with reference to the attached drawings.

[0036]FIG. 1 is a schematic diagram of a stereoscopic image display system according to an embodiment of the present invention.

[0037]Referring to FIG. 1, the stereoscopic image display system includes liquid crystal shutter glasses 110 and a stereoscopic image display apparatus 120. The stereoscopic image display apparatus 120 employs an LCD device or an organic light emitting diode (OLED), and alternately displays repeated left-eye images and repeated right-eye images. The stereoscopic image display apparatus 120 adjusts a turn-on cycle and a turn-on duration of a backlight device formed of a plurality of light emitting segments in synchronization with the repeated left-eye and right-eye images. In an exemplary embodiment the backlight device of the stereoscopic image display apparatus 120 may operate at 120 Hz or 240 Hz.

[0038]The liquid crystal shutter glasses 110 alternately open an...

Abstract

Provided are methods and apparatuses for displaying a stereoscopic image. The method includes alternately generating repeated left-eye images and repeated right-eye images; turning off a backlight unit during a period in which a left-eye image and a right-eye image are mixed and turning on the backlight unit during a period in which only one of the left-eye and right-eye images is displayed; and controlling a left-eye shutter and a right-eye shutter of shutter glasses during a period in which the backlight unit is turned on.
